Wi-Fi, ethernet and a mobile backup: what actually changes

[Shadow Trader]

A scalper on Wi-Fi may not notice the problem until a bad moment. Wireless connections add variable delay and occasional drops that a cable doesn't. The average ping looks fine, and the worst-case ping tells the real story.

A wired connection removes that variability. Ping can be higher on average on a cheap line, but it's steadier, and steadiness often matters more than speed.

A mobile hotspot as a backup is a good idea, with a few cautions. Switching connections mid-session can drop the platform's link to the server. Mobile networks add more latency and more jitter. Carrier-grade NAT can cause odd disconnections.

A pair of habits help. Testing the backup in advance, with a live platform, not just a speed test. And knowing the procedure for open positions if the main link fails, which means having the broker's phone number handy and a mobile app logged in.

A speed test measures download capacity. A scalper needs low and consistent latency and no packet loss, which is a different thing.

What backup arrangement has actually been tested under live conditions?

The worst-case ping telling the real story is the key point. A wired connection removes the variable delay, and a mobile hotspot tested in advance gives a backup that can close positions if the main line drops.
